Frictional force is not a fundamental force but rather an emergent force arising from interactions between particles.

General relativity is a theory of gravitation that describes the universe at its largest scales.

The Higgs boson is associated with the weak nuclear force and is responsible for giving mass to elementary particles.

Sound waves are mechanical waves and not a type of electromagnetic radiation.

Dark energy is believed to be the dominant force driving the accelerated expansion of the universe.

Gravitational lensing is the bending of light due to the gravitational field of massive objects.

Photon is a fundamental particle of light and not a subatomic particle.

Astrophysics is the branch of physics that deals with the study of celestial objects and phenomena.

The strong nuclear force is responsible for binding protons and neutrons together in atomic nuclei.

Quantum entanglement involves the linking of particles such that the state of one particle cannot be described independently of the other.

The cosmic microwave background radiation is the leftover radiation from the Big Bang, the event that is believed to have created the universe.

Planetary nebula is a type of nebula, not a type of galaxy.

Cosmology is the branch of physics that deals with the study of the origin and evolution of the universe.
